At least in Lithuania, I expect this is also applicable in some other countries, it is popular to “accumulate” returned to grid solar energy in energy provider grid. You do not get any instant money for returning energy to grid, but, for example, you can get amount (or part of, depending on your contract with provider) of accumulated energy for much less price (during night or winter season for heating).
Returned collected energy (price) has priority to purchased energy price in price calculation.
Needed properties:
- Setup retrieved energy price similar to " Grid consumption" or “Return to grid”.
- Possibility to manually adjust collected collected energy quantity.
- Date when collected energy is being nulled automatically (this happens once a year)
- What percentage or returned energy is being collected (you can choose to leave agreed percentage of electricity to provider for returning left collected energy for free).
